- This invention relates to devices for opening and closing motor vehicle windows, and in particular a lever actuating gear journaled in a bracket mounted on a motor vehicle door and positioned to mesh with the pinion on the conventional handle shaft with which the window is raised and lowered.

The purpose of this invention is to expedite opening and closing windows of motor vehicles whereby instead of winding a crank it is only necessary to push or pull a knob on the end of a lever extended from the side of the vehicle.

With the conventional type of motor vehicle window operator, it is necessary to turn a small crank and in some vehicles it is necessary to turn the crank three revolutions in opening or closing a window. With a mail carrier serving 100 or more mail boxes considerable time is lost in opening and closing the window at each box. With this thought in mind this invention contemplates the use of a comparatively small pinion on the shaft of the window opening crank and a relatively large gear journaled on the door and meshing with the pinion whereby a small movement of the gear by a hand crank turns the pinion through a plurality of revolutions whereby a window in combination with which the device is used is opened or closed by pushing the hand lever forwardly or pulling it backwardly with the lever moving to an angle of substantially 45 in either direction.

The object of this invention is, therefore, to provide mechanical means for expediting closing and opening movements of a motor vehicle window glass.

Another object of the invention is to provide an improved motor vehicle window operator that is adapted to be installed in motor vehicles now in use without changing the design or structure thereof.

A further object of the invention is to provide auxiliary operating means adapted to be used in combination with conventional motor vehicle Window operators whereby the windows may be opened and closed with comparatively short movements in which the auxiliary device is of a comparatively simple and economical construction.

With these and other objects and advantages in view the invention embodies a pinion positioned on a crank shaft of a conventional motor vehicle window operating mechanism, a gear journaled on a mounting plate on the door and positioned to mesh with the pinion, and a hand lever with a knob on the end extended from the gear and positioned to turn the gear.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is an elevational View looking toward the inner surface of a door of a motor vehicle with parts broken away and illustrating the auxiliary window operating mechanism installed behind the upholstery of the door.

Figure 2 is a View similar to that shown in Fig. 1 with the parts shown on an enlarged scale and with the outer layer of upholstery omitted.

Figure 3 is a vertical section taken on line 3--3 of Fig. 1 also showing the auxiliary door operating mechanism, and with the parts also shown on an enlarged scale.

Figure 4 is a section taken on line 4-4 of Fig. 2 illustrating the mounting of the pinion on the operating crank shaft of the conventional window operating mechanism. v

Fig. 5 is a plan view of the pinion I0; and

Fig. 6 is a plan view, on a reduced scale, of the gear I2.

Referring now to the drawings wherein like reference characters denote corresponding parts the auxiliary motor vehicle Window operating mechanism includes a pinion I0 adapted to be mounted on a shaft II of the conventional Window operating mechanism, a gear I2, journaled by a pin I3 on the mounting plate I4 and a lever I5 mounted on the gear I2 with rivets I6 and having a knob Il on an extended end thereof.

As illustrated in Fig. 3 the plate I4 upon which the gear I2 is pivotally mounted by the pin I3 is secured by screws I8 to a panel I9 of a door, as indicated by the numeral 20, with the parts positioned behind upholstery 2| and with the offset end 22 of the lever I5 extended through an opening 23 in the upholstery.

The lower end of the plate I4 is provided with a flange 24 which is connected to the lower edge of the plate with a web 25 and the flange 24 is provided with a stud 26 that extends into the bore in the pinion IIJ and abuts the end of the shaft Il. The pinion I0, which is positioned on a square section 28 of the shaft Il is retained between the ange 24 and a shoulder 29 on the shaft.

In applying the invention the conventional crank handle for the window mechanism is removed from the shaft Il. The pinion I0 is then positioned on the shaft I I to replace the handle. Thus when gear I2 is rotated by the lever I5 the shaft II will be caused to rotate to operate the conventional window mechanism to cause the window to be raised and lowered.

With the parts arranged in this manner and 3 Y with the diameter of the gear l2 larger than that of the pinion I a comparatively short movement of the knob I1 on the extended end of the lever l 5 rotates the pinion I0 sufficiently to open or close a window.

It will be appreciated that the design and arrangement of the parts is only typical as the parts may be formed ofl different designs and arranged Jin dier'ent positions to correspond 'with the Vehicle 'r door of a vehicle upon which the device is used.

It will also be understood that other modications may be made in the design and arrangementof the parts without departing from the spirit of the invention.

What is claimed is: K Y

l. A Window operator comprising an elongated plate having a centrally positioned flange paallel to and spaced from one end and said iiange connected to the plate with fa web; ls'aizi vflange also having a s'tud on the side thereof 'facing the plate and abutting the en'd of the' shaft of a Window raising mechanism, a pinion mounted on the shaft of the Window -rai'sing mechanism and having an opening in one end for receiving the stud positioned against theV llange andl `'extended through th plate,A a gear ouir-'aled on the .plate and positioned tfmesn 'with the' pinion and a handle extended romthe fae'eof the geyr.

2. In a motor vehicle 'p'at, the combination 'which comprises a Wall hav-ing Aan opening in th'e upper part thereof, a glass 'panel slidably mounted in theA Wal-l and positioned 'to extend across said opening o the wall', a Window operating mechanism mounted in the Wall and having a shaft extended therefrom for operating the glass panel, a plate mounted in the Wall land positioned adjacent the shaft, 'said plfat'e havingV a flange connected `-to and v'extended A'from the lower end. said Iiiang'e having a stud extended lli therefrom, a pinion mounted on the shaft and positioned by said stud, a gear rotatably mounted on the plate and positioned to mesh with the pinion, and a lever attached to the gear providing a handle.

3.
